IPC: B65B35/44
Filed: 1952-10-31
Abstract: 741,300. Endless conveyers. INTERNATIONAL CELLUCOTTON PRODUCTS CO. Oct, 31, 1952 [April 14, 1952], No. 27404/52. Class 78 (1). [Also in Group XVII] Articles for packaging are continuously supplied to apparatus including a plurality of serially arranged holding stations for the articles of which predetermined quantities accumulate at-the final station preparatory to being removed for packaging. Sanitary napkins 21 are fed from a magazine 23 on to a conveyer 24 which passes round a driven drum 26, each napkin being taken from the drum by pins 54 on a pick-up wheel 38 and transferred to a stationary platform 52 from where the napkin is pushed by a pair of L-shaped fingers 66 on to a gate 30 at the top of a vertical bin 60 formed by posts 58 and vertical plates 88. The fingers 66 are pivoted on endless chains 64 and each finger is normally caused to project outwardly by the engagement of a roller 82 on a cam-plate 84. After pushing a napkin on to the gate 30, the fingers are tilted clear of the napkin by springs 170, the rollers 82 moving into cut-out portions 168 of the cam-plates. The gate 30 consists of two sections 92 which are caused to swing outwardly by the action of cams 104 almost simultaneously with the placing of the napkin on the gate, the napkin falling on to a lower gate 32 and the sections 92 then swinging closed to receive another napkin. After a predetermined number of napkins, e.g. three or four, have accumulated on the gate 32, a cam 126 causes two sections 116 of this lower gate to swing out and back, thus allowing the napkins to fall on to a stationary ribbon-like member 34 of a conveyer 90 which has pivoted pusher members 152 provided with rollers which engage a cam plate 160. After a dozen napkins have been stacked in the bin 60 on the member 34, a pair of the pusher members 152 moves the stack to a point beyond shafts 138 carrying conveyer sprockets at the end of a trough 137, the fingers then dropping back, thus leaving the stack undisturbed ready for packing. The apparatus is operated by an electric motor 172 via belt, gear and chain drive. Specification 731,304 is referred to.

Abstract: 519,724. Porous fibrous compositions. TURNER & NEWALL, Ltd., and WILSON, G. Sept. 22, 1938, No. 27689. [Classes 70 and 87 (ii)] [Also in Group VIII] Heat insulation having a cellular structure is obtained by agitating in a hollander or the like a dilute liquid stock of vegetable fibres consisting predominantly of peat, concentrating the stock, chemically generating a gas in it without chemically affecting the fibres, and drying the stock in the desired shape while retaining the gas in it. The gas may be generated by the addition of an acidic substance such as aluminium sulphate and a carbonate or bicarbonate, e.g. sodium bicarbonate. A foamstabilizing agent such as saponin or liquorice may be. added to retain the gas in the stock. The fibres may be rendered water-repeHent by adding an emulsion of bitumen, wax, or oil, or a mixture of soap and aluminium sulphate. Vermin-proofing agents such as cresol and fire-resisting. agents such as sodium ammonium phosphate, ammonium phosphate, or asbestos, may also be added. The finished product may be coated with Portland, gypsum, or magnesium oxychloride cement. In an example, a mixture of peat 85 per cent., and wood pulp 15 per cent. is beaten with water in a paper beater at a concentration of 0.6-1 per cent., and asbestos with soluble soap and aluminium sulphate added. The mixture is concentrated to 10-14 per cent., and for each 100 parts of the original dry stock there are added aluminium sulphate 11 parts, saponin 0.4 parts and sodium bicarbonate 8.5 parts, and the mixture agitated. Vermin-proofing and. fire-proofing agents may be added at this stage. The mixture is poured into a mould with a filter .bottom and then dried in a humid atmosphere, the humidity being gradually reduced, first at. 250‹F. and finally up to 300‹F. ,

Filed: 1950-11-13
Abstract: Polyphosphoric acid esters are prepared by reacting a derivative of a poly basic phosphoric acid which is at least doubly esterifiable with one or more polyhydric, preferably dihydric, aliphatic or aromatic alcohols, in such proportions that for each molecule of acid derivative there are two alcoholic hydroxyl groups.  If trebly esterifiable acid derivatives are used, the remaining reactive acid group may be reacted subsequently or simultaneously with water, inorganic or organic compounds such as monohydric alcohols, preferably with 8 to 18 carbon atoms, alkylated phenols and naphthols, resin alcohols, oxyalkylated hydroxyl or carboxyl compounds such as polyglycolethers of fatty alcohols or phenols, stearoyl glycols and distearoyl glycerine, and ethylene oxide. Remaining hydroxyl groups from the ethylene oxide treatment may be reacted with chloroacetic acid.  Dihydric alcohols referred to are octadecanediol and polyethylene glycols of molecular weight up to 4,000.  The products are surface active and thickening agents and components for ointments and creams.  In examples: (i) a polyglycol of molecular weight 700 dissolved in benzene is reacted with phosphorus oxychloride for 90 minutes and the product reacted with water to give a wax-like mass after removal of solvent and cooling; (2) a polyglycol of molecular weight 450 is reacted with phosphorus oxychloride in the presence of phosphorus trichloride and the product esterified with a fatty alcohol mixture of mean molecular weight 186; (3) a polyglycol of molecular weight 300 and xylenol are dissolved in trichlorethylene and esterified with phosphorus oxychloride for two hours, the reaction then being stopped by blowing out with steam.
